SELF-CONTAINED HYDROGAR-BON-LAMP.

Application filed June 10, 1914. 7 Serial No. 844,218.

pipes, tubes, or hollow wire; and the ob ject of my invention is to provide a lamp of this kind so constructed that in outward appearance the lamp will resemble an ordinary gas lamp, or a lamp fed by a hollow wire.

A further object of the invention is to so construct the lamp and reservoir that while the fluid contained in the reservoir will be fed to the lamp in an unrestricted manner,

the reservoir itself will appear more as an ornamental part of the device than a reservo1r. To carry out the objects of my invention I have located the reservoir in a peculiar position relative to the lamp proper; and as a consequence of such location have provided special means for feeding the fluid to the lamp.

The invention is illustrated in the accompanying drawing, in which- Figure 1, is an elevation of a lamp constructed in accordance with my invention, with the reservoir, and part of the feeding tubes in section to show the construction; Fig. 2, is a view similar to Fig. 1; but showing my invention in connection with a double lan1p;andFig. 3, is a view similar to Fig. 1, but showing a different form of lamp, or the reservoir thereof.

In the drawing similar numerals of reference refer to like parts in each of the views. In practice I make the hydrocarbon lamp in three parts comprising a reservoir 4,

bracket 5, and lamp proper 6, which is preferably provided with a'shade7, of a pattern harmonizing with the reservoir 4. i

As constructed, the bracket 5, carries the lamp proper 6, and in addition thereto is the feed tube through which the hydrocarbon fluid (not shown) is fed to the lamp proper from the reservoir 4. In order that this feed tube and bracket combined may not detract from the appearance of an ordinary light fixture it enters the reservoir 4, at one side;

and continues within said reservoir to the stay 8, which may carry a T-connection 9, which the interior part 10, of the bracket 5, enters whereby the tube 10, is in communication with the interior of the stay 8, or the bottom part 12, thereof which extends to the bottom of the reservoir 4, and is provided adjacent to said bottom with a port 13, through which the hydrocarbon fluid may enterthe part 12, and flow through the same and the bracket to the lamp properx6, where it may be gasified and burned, as will be understood. r

In making the reservoir 4, it is customary to make the same in two parts. As shown, the upper part 14, is connected with the lower part 15, by a joint 16, of any desired construction. It will be observed, however, that the reservoir 4, is made of a contour to harmonize with the shape of the lamp shade which is mounted on the lamp proper. In use air isforced intothe reservoir through the valve 17, until there is'considerable pres sure within the reservoir. This pressure would be likely to distort the shape of-the Specification of Letters Patent. Patented June 15, 1915. I

reservoir as constructed owing to the fact that the reservo r is made to harmonlze with the shape ofthe shade rather than of a shape to stand pressure in all directions without distortion. To prevent the distortion of the reservoir I mount on the bottom of the stay 8, without the reservoir a nut 18; and above the part 14, of the reservoir I mount a collar 19. These parts are in close contact respec:

tively with the top and bottomof the reservoir whereby spreading is prevented. Thus the stay serves to hold the reservoir in shape, and also serves tocarry the oil, or hydrocarbon fluid from the bottom of the reservoir to' the bracket'so that it may be fed to the lamp.

The entire construction is simple to manufacture, easy to operate, and attractive in appearance. v V

In operation, the reservoir 4, is filled to the desired level through the port in which the air valve 17 is mounted. The air valve is then placed in position, and the reservoir proper 6 so that the lamp may be operated as an ordinary gas, or gasolene lamp, as previously described. 7 y

In Fig. 2, there are two lamps 6, 6, carried by two tube bracketso, 5, respectively,

the bracket, or brackets.

mounted on a single reservoir l. The stay 8, is provided with the collar 19, and nut 18, as in Fig. 1, whereby the parts 14;, and 15, of the reservoir are firmly held together. There are two parts 10, 10, connecting the respective bracket tubes 5, with the feed tube, 12; and a cross 20, is mounted on the stay 8, so that both of the tubes 10, 10, may communicate with the feed tube 12, and receive the fluid which enters therein through the port 13. The operation of this lamp is just the same as that described with reference to Fig. 1, with the exception that the lamps proper, and connections are duplicated.

While I have described the part 8, and 8, as a stay, as shown in Fig. 2, the upper part connecting with the cross 20, is a rod, and the lower part 12, is a tube. This is the desirable construction since it is not desirable that the fluid travel within the stay higher than the outlet, or outlets leading to it is immaterial, however, whether a rod be used for the upper part of the stay, or a tube as in either construction the collar 19, and nut 18, will be carried to hold the reservoir in proper Ttis evident, too, that if the upper part were 'a tube instead of a rod, it could be pluggedat the point of connection with the T 9, or cross 20, so that the fluid would not pass above these connections.

In Fig. 3, I have shown a different form of device, or lamp. The device shown is adapted to be mounted against wall. In all the devices shown, the shade 7, is the same, as well as the lamp proper 6, and bracket 5. In Fig. 3, however, the reservoir "I is made with a side 21, adapted to rest against a wall. The stay 8 however, is different from that previously shown and described with reference to Figs. 1, and 2, in that the part 10 forms the connection with the bracket tube 5, and the rod extension, or part completing the stay, is connected with the part 10 by the horizontal part of the T 9, instead or" the vertical part, as in 1. The feed tube 12, does not extend through the bottom of the reservoir, but terminates adjacent to the bottom whereby the open end of this tube forms the port 13, for the entrance of the fluid. The side 21, is made i concave, as shown so that the nut 18, can lie within the plane of the bottom, and not interfere with the position of the reservoir against the wall. The collar 19, is used on the part 10 and forms with the nut 18, the means on the stay to hold the reservoir in shape in the same manner asdescribed in connection with the previous figures.

It will be observed that all the devices shown are provided with supports, as described in a companion application filed herewith so that they may rest on a support, as 22.

It is evident that various changes can be made in both shape, and the construction of the parts without departing from the spirit of my invention.

My purpose is to provide a hydrocarbon lamp which will be self-contained, but of an appearance that will be attractive in use. As this involves the construction of a reservoir so shaped that pressure from within is liable to cause distortion it becomes necessary to provide means to prevent this distortion. By providing the means described, and shown, distortion is prevented. At the same time, connection can be made with the reservoir in a way not to detract from the artistic appearance of the lamp; and the entire contents, or substantially so, can be fed to the lamp.

T'claim:

1. A hydrocarbon lamp 7 comprising a lamp proper and a distortable reservoir, a stay passing through said reservoir whereby the same is held against distortion, and a feed tube connected with said stay at substantially right angles, said lamp being in communication with said reservoir through said stay.

2. A hydrocarbon lamp comprising a lamp proper, and a distortable reservoir, a stay passing through said reservoir and binding the parts together, and a feed tube connected with said stay at substantially right angles, a part of said stay being a tube, and said feed tube being in communication therewith and with said lamp.
